Next-generation firewalls (NGFWs) filters network traffic to protect organizations from internal and external threats. With maintaining features of stateful firewalls such as packet filtering, IPsec and SSL VPN support, network monitoring, and IP mapping features, NGFWs possess deeper content inspection capabilities. These capabilities enable it to identify and block attacks, malware, and other threats. NGFWs provide organizations with SSL inspection, application control, intrusion prevention, and advanced visibility across the entire attack surface.

As the threat landscape rapidly expands due to co-location and multi-cloud adoption, and businesses are growing to satisfy escalating customer needs, traditional firewalls are falling further behind, unable to offer protection at scale. On the other hand, NGFWs do not only block malware but also include paths for future updates, giving them the flexibility to evolve with the threat landscape and keep the network secure as new threats arise. Next-generation firewalls are a vital component of implementing network security.
